Hi David,
The following pull-request contains BPF updates for your *net-next* tree.
We've added 37 non-merge commits during the last 1 day(s) which contain
a total of 67 files changed, 741 insertions(+), 252 deletions(-).
The main changes are:
1) bpf_xdp_adjust_tail() now allows to grow the tail as well, from Jesper.
2) bpftool can probe CONFIG_HZ, from Daniel.
3) CAP_BPF is introduced to isolate user processes that use BPF infra and
to secure BPF networking services by dropping CAP_SYS_ADMIN requirement
in certain cases, from Alexei.
